Electronic Device

1. An electronic device comprising: an outer housing including a first surface facing in a first direction, a second surface facing in a second direction opposite to the first direction, and a side surface surrounding at least a part of a space between the first surface and the second surface; an inner housing mounted inside the outer housing; an opening formed on at least one of the first surface, the second surface, or the side surface of the outer housing; a first channel part extended from the opening between the outer housing and the inner housing; circuitry mounted inside the inner housing; a second channel part provided in the inner housing, connected to the opening through the first channel part, the second channel part including a first channel extended from the opening directly to the circuitry through the first channel part and a second channel provided in a vicinity of the first channel, wherein the second channel part is extended to the opening through a connection space of at least a part of the first channel part and wherein the second channel part is extended to an inner space of the inner housing; and a stacked member mounted inside the first channel part to: seal the first channel part; and restrict introduction and discharge of water or moisture except for air into and from the first channel and the second channel.

2. The electronic device of claim 1 , wherein the circuitry is at least one of an audio for an audio communication, a camera, a connection circuit connected to an external device, a button for applying an input, or illumination circuitry for emitting light.

3. The electronic device of claim 2 , wherein the opening is at least one of a shape-matching hole for mounting the circuitry or a functional hole for mounting the circuitry, while connecting the circuitry to the outside of the electronic device.

4. The electronic device of claim 2 , wherein the audio includes at least one of microphone or speaker.

5. The electronic device of claim 1 , wherein the stacked member comprises: a sealing member for sealing the first channel part; and a foreign-material blocking member disposed between the sealing member and the second channel part.

6. The electronic device of claim 5 , wherein the foreign-material blocking member comprises: a first member for tightly sealing the first channel; and a second member mounted to: allow introduction and discharge of air into and from the second channel; and restrict introduction and discharge of water or moisture into and from the second channel.

7. The electronic device of claim 6 , wherein the first member is formed of a first material and the second member is formed of a second material different from the first material.

8. The electronic device of claim 5 , wherein the sealing member comprises: a sealing body mounted in the opening; a first hole formed on the sealing body in correspondence with the first channel; a second hole formed in a vicinity of the first hole on the sealing body in correspondence with the second channel; and a sealing engagement surface protruding toward an inner surface of the opening from the sealing body, around the first hole and the second hole, for closely contacting an inner surface of the housing.

9. The electronic device of claim 8 , wherein a connection space is provided between the first hole and the second hole for forming a connection opening connecting the second channel to the opening.

10. The electronic device of claim 1 , wherein the opening comprises at least one of a shape-matching hole or a functional hole.

11. The electronic device of claim 1 , wherein a connection opening is provided between the first channel and the second channel for connecting the second channel to the opening.

12. The electronic device of claim 11 , wherein a sealing member is provided in the opening for sealing around the first channel and the second channel.
